默认选中

使用selected属性

当然selected是选中, disabled是禁用

<div id="demo2" class="xm-select-demo"></div>

<script>
var demo2 = xmSelect.render({
    el: '#demo2', 
    data: [
        {name: '水果', value: 1, selected: true, disabled: true},
        {name: '蔬菜', value: 2, selected: true},
        {name: '桌子', value: 3, disabled: true},
        {name: '北京', value: 4},
    ]
})
</script>

使用initValue进行初始化

initValue的优先级大于选项中的selected

<div id="demo1" class="xm-select-demo"></div>

<script>
var demo5 = xmSelect.render({
    el: '#demo1', 
    initValue: [4],
    data: [
        {name: '水果', value: 1, selected: true, disabled: true},
        {name: '蔬菜', value: 2, selected: true},
        {name: '桌子', value: 3, disabled: true},
        {name: '北京', value: 4},
    ]
})
</script>
